Filter by:The purpose of this study is to determine the prevalence of plaque disruption and to assess the composition of disrupted plaques in patients with myocardial infarction (MI) and non-obstructive coronary artery disease (CAD) using optical coherence tomography (OCT). Additionally, cardiac magnetic resonance imaging (CMR) will be used to detect myocardial abnormalities, which will be correlated to OCT findings to gain insight into the mechanisms of MI in patients with non-obstructive coronary artery disease (i.e. "open arteries").
The conceptual hypothesis of this study is that primary angioplasty is superior to a combined strategy of immediate thrombolysis followed by routine angioplasty in patients with ST-segment elevation acute myocardial infarction (STEMI), even with the inherent delay of the transfer of these patients.
The purpose of this study is to compare early vessel healing after implantation of SYNERGY drug eluting stent (DES) or BioMatrix NeoFlex DES at one and three months in two cohorts.
Current methods based on traditional Cardiovascular risk factors are not clinically useful for identifying Type 2 Diabetes patients at risk of developing acute Cardiovascular ischemic events (ie.myocardial infarction or stroke). In addition, Cardiovascular ischemic events in Type 2 Diabetes population have worse prognosis than in general population. In fact, there is sufficient experimental evidence indicating that diabetes exaggerates the deleterious effects of ischemic events and worsens their outcome. A prolonged sub-clinical phase exists before a Cardiovascular event occurs in Type 2 Diabetes patients. Therefore, new strategies aimed at identifying those patients with this subclinical Cardiovascular Diabetes and, consequently, more prone to develop Cardiovascular events is a challenge to be met.
The purpose of this study is to assess the impact of frailty as a multidimensional risk factor on the outcomes of adult cardiac and vascular surgery. For the purpose of defining patient frailty a multimodal questionnaire has been developed including measurement of psychological, socioeconomical, neurological and behavioral aspects. This study also features an investigation of the possible relationship between sudden regional weather changes, individual meteorological susceptibility of the patients and the outcomes of adult cardiac and vascular surgery.
Cerebral infarction is the most common form of stroke (80% of strokes). Stroke is the first cause of acquired disability, and the 2nd cause of dementia and death. The only approved treatment in the first 4.5 hour is intravenous rt-PA thrombolysis (Actilyse ®) whose objective is recanalization of occluded artery and reperfusion of the brain parenchyma. Few patients are treated (1-5%) and they keep disability in 50-60% of cases. This handicap is mainly correlated to the final infarct size. The objective of neuroprotective treatments is to reduce the final size of the cerebral infarction. The per-conditioning remote ischemic (Per-CID) showed a neuroprotective effect in cerebral ischemia by reducing the final size of cerebral infarction animal models. The per-CID corresponds, in cases of cerebral ischemia, to iterative ischemia realization of a member with a cuff. In humans, the per-CID has shown a cardioprotective effect in a randomized control trial involving 250 patients within 6 first hours of myocardial infarction and candidate for primary angioplasty.
This study focused on the effect of Danhong injection on microcirculation in the treatment of patients with STEMI(ST-elevation myocardical infarction) after the PTCA surgery.
Angina is caused by narrowings or blockages within coronary arteries. Coronary angioplasty and stenting is performed for people with angina to improve the blood supply to the heart by placing metal tubes within the artery using balloon inflation. The procedure risks small but significant damage to the heart muscle downstream of the balloon. Glucagon like peptide 1 (GLP 1) is a naturally occurring hormone secreted by cells in the gut in response to food. It acts by stimulating the release of insulin. In the heart it acts to increase glucose uptake into cardiac muscle. GLP−1 can protect the heart and improve heart muscle performance in people with coronary artery disease in physiological studies. This study which assesses whether GLP−1 protects the heart during coronary angioplasty and stenting. The hypothesis is that GLP-1 given during elective coronary angioplasty and stenting will reduce cardiac troponin rise (a measure of heart muscle damage) compared to placebo.
Heart imaging with magnetic resonance imaging (MRI) provides detailed insights into heart function and injury. The nature and significance of heart injury after a heart attack is incompletely understood. We propose a 'natural history' study of heart attack injury using contemporary MRI methods. In a large hospital in the West of Scotland, heart attack patients will be invited to have at least two MRI scans and also continue with life-long follow-up. The results from the MRI scans will be assessed with all of the other clinical information obtained at the time of the heart attack and during follow-up. The results of our study should provide new insights into heart attack injury and these results should help improve how heart attack patients should be treated.
